Strategies To Improve The Ability Of Chemical Problem-Solving In Senior High School

Globalization and market economy reforming lead to speeding up the development of the knowledge economy era.Pressure for students' learning and future competition has been increased by the adjustment of industrial development layout and the increasingly fierce market competition trend,which puts forward higher requirements for contemporary students' logical ability,creativity and innovation.Meanwhile,the new curriculum reforming scheme and the annual renewal of the new curriculum standard,which set higher standards for obejectives and methords of Chemistry teaching in high schools,clearly emphasize the cultivation of students' overall quality and the training goal of practical application-oriented talents.Hereby,for senior High School students,development of problem-solving ability in Chemistry not only realize the mutual interchange between discipline knowledge and practical skills,but aslo lay solid foundation for the realization of the goal of application-oriented innovation talents training.For research pupose,this paper focuses on the students' obstacles of problem-solving and their reasons.It bases on subjective angle of students who actively to look for problems-olving difficulty,and furhter explore their reasons with an objective view.It is to find effective strategies to improve students' ability to solve chemical problems,and to really improve the ability of high school students to analyze problems and chemical calculation.It helps students bear the knowledge structure of subject in mind,so as to increase students' participation in chemistry class,improve teaching quality and efficiency and guide students to develope goodthinking habits and study habits.Furthermore,it helps to improve students' s logical ability and promote the students' core qualities in Chemistry.On the aspect of research methods,firstly,this paper uses the method of literature review to summarizes the current research situation in this field,and clarifies the creative ideas of this paper by reading a large number of domestic and foreign relevant fields of experts and scholars' literature,writing and research results.It seeks the foundation and the core branch of the theory to improve the academic research value and the practical appilication effect and research value of the study.Secondly,this paper,with the questionnaire survey on 237 students,analyzes generality and diversity of problem-solving based on students' gender and academic achievements.Thirdly,this paper,adopting empirical analysis method,analyzes the main types of problem-solving difficulty based on the test results of diagnostic test questions for 110 students selected from three universities.It finds out that there are five kinds of diffculties inculding examination,calculation,knowledge,thinking and psychology.Besides,it explores the ability of different students to break through the obstacles of solving chemical problems from three angles: grade,gender and academic achievements.Finally,with the method of practical research,this paper explores effective teaching strategies to improve senior high school students' ability to solve chemistry problems according to the above-mentioned survey and diagnosis test.It hopes to lay a good foundation for their application in the future teaching practice,and provide valuable reference value for teaching.With regard to the research results,this paper closely combines the discipline training scheme with the actual situation of teaching based on the background of the continuous and in-depth advancement of the new curriculum reforming.With the help of previous research results and related academic theories,this paper not only provides a solid argument for this paper,but also finds out the main types of reasons leading to students' s diffculty in problem-solving by questionnaire and empirical analysis,combining with the important types of college entrance examination in recent years and the required knowledge points for the preparation of diagnostic test papers.It also promotes solving strategies around the representation of core problems,whichstrengthens the evidence of the solving strategies,and is devoted to the improvement of both students' ability of solving chemistry problems and comprehensive thinking of subjects from a long-term perspective.Under the professional guidance of the supervisor and the support and cooperation of many senior high school teachers and students,this paper preliminarily grasps the main types and characteristics of the problem-solving obstacles of students of different grades,gender and academic level.It also explores the key cause of the problem-solving obstacles of senior high school students and its specific reasons,and puts forward some effective measures to solve students' problems in high schools.However,with the limitations of research time,research conditions and personal abilities,some problems need to be further studied,supplemented and perfected in future study and work,with hopes of important support for the vast number of teachers in teaching practice.
